Marker set POSCA PC-8K by POSCA — 8 basic colors, opaque water-based pigment paint markers, bullet tip

POSCA PC-8K is a set of eight opaque water-based pigment paint markers with bullet tips, designed to deliver matt, solid coverage on a wide range of surfaces. The markers produce consistent, permanent-looking lines and fills on paper, cardboard, wood, ceramics and many porous and treated non-porous materials. The PC-8K set includes eight basic colors selected for general drawing, illustration, labeling and craft applications where controlled strokes and reliable opacity are required.

Advantages

The POSCA PC-8K markers combine a water-based pigment formulation with a durable bullet tip to give stable, clog-resistant flow and uniform color application. Their opaque pigments provide high coverage without the strong solvent odor associated with some paint markers, and the matte finish reduces glare for photographs and display work. Bullet tips offer a predictable line width suitable for lettering, outlining and filling small areas, while the quick-drying paint minimizes smudging on many common surfaces.

Suitable for

• Illustration and sketching on paper and cardstock
• Labeling, sign-making and marking on cardboard and wood
• Small craft and DIY projects on ceramics, terracotta and painted surfaces
• Mixed-media artwork and layering where opaque coverage is needed

When it may not be suitable

These markers are formulated for opaque coverage and perform best on porous or prepared surfaces; adhesion and durability on bare plastics, very glossy laminates or untreated metal may be limited without surface preparation. For very fine detailed work or extremely broad coverage, a different tip size or larger marker may be preferable.

Key specifications

• Consumable type: water-based pigment paint
• Tip style: bullet tip for controlled strokes and medium line width
• Finish: opaque, matte coverage
• Color set: eight basic colors suitable for mixing and layering
• Drying behavior: quick-drying on most porous surfaces

How to use

Shake each marker well before use to mix the pigment. Press the tip gently on a scrap surface to prime the paint flow until color appears. Apply with steady pressure for even lines or fill areas using cross-hatching and multiple passes for fuller opacity. Allow layers to dry between applications to prevent lifting; on non-porous surfaces, test adhesion and allow extended drying or bake/heat-set methods if appropriate for the material.

What to consider before purchase

• Check the target surface — porous or prepared surfaces give best adhesion and coverage
• Verify whether a different tip size or a larger set is needed for finer detail or broader coverage
• Consider testing on a small area if using on glossy or non-porous materials

Usage recommendations

For consistent results, store markers horizontally and recap them after use. For layered effects, let each layer dry fully before applying the next. When working on ceramics or other non-porous items, perform a small adhesion test and consider sealing the finished work with an appropriate clear coat if durability is required.
